Potentiometer connected to USBExpansion Card

Hi everyone,

Since it has been such a long time since I last connected a Potentiometer and used it in SIOC, I am slightly confused on the process of using a Pot connected to the USBExpansion Card.

In the past, all my Potentiometers were connected to my USBDCMotors Card. This Pot, however, is connected to the USBExpansion Card (Input #4).

This is my SIOC.ini file:

I need to know which entry I need to add to use the Potentiometers off've the USBExpansion Card. Unfortunately, the manual only tells you how to configure Pots for the Controlador.exe program, which is obviously useless if you want to use it in SIOC.

The USBExpansion Card is Index 0, Device 18. The Pot is #4. Any suggestions?

Cheers,

Jack

Jack,

Found this in the SIOC docs:

IOCARD_ANALOGIC

With this link we can read from the USB Expansion card analogue axes.
The values from the A/D converter is stored in the variable. Values vary between 0 and 255.

Attributes :
Name Assigns a symbolic name to a variable.

Input Sets the axe (#1-4).
PosI Sets the left position (normal value is 0)
PosC Sets the center position (normal value is 127)
PosR Sets the right position (normal value is 255)

Example:

Code:

---

Var 2032, name POT1, Link IOCARD_ANALOGIC, Input #1, PosL 1, PosC 128, PosR 255

---

Here is another one...

Code:

---

// Ailerons axle

Var 0001, Link IOCARD_ANALOGIC, Input #1, PosL 0, PosC 128, PosR 255
// Input #1 means analog connector #1 in USB card. Without “#” would mean //digital input
{
  L0 = V0001 * 129    // Potentiometer movement calculation
  V0002 = L0 - 16512
}

// Simulator ailerons (offset from -16383 to 16383)
Var 0002, Link FSUIPC_OUT, Offset $0BB6, Length 2

Thanks to much for that Perik! It has worked a treat! Cheers!
